I My invention relates to a new and useful jacquard punching machine and 1t relates more particularly to a novel machine for stamping pattern cards for use in connection with jacquard controlled textile machinery, although my invention is also apspaced relation to each other.

'My iiiventionconsists of a novel combination or punching mechanism, means to guide and intermittently to propel a piece of sheetmaterial' with respect to said punching mechanism "at a predetermined rate and an adjustable pattern mechanism to operate iipon the intermittently propelled sheet ma- ,terial according to a predetermined though variable sequence or patteri i.

For the purpose of illustrating my invention I have shown the accompanying drawings one form thereof which is at presentjp'reterred by me, since t-he same lias been found in'practice to give satisfactory and reliable results, although it isto be'understood thatthe various instrumentalities of which invention consistscan be variously arranged and organized and that my nveni/ OH is. not limited to the precise arrangeineiit aiid organization of the nstrumentalities as herein shown and described.

In carrying out my invention 1 may utilize a punch press of any conventional construction having a base 1, with an overhanging frame 2, upon which is slidably mounted a vertical punch slide 3 in usual manner, and in the upper'part of which a pair of main bearings and 5 are provided, in which is journalled a crank or cam si 1ft 6 having a central eccentric cam or crank The cranlr or eccentric cam '7 is intera clutch bolt orlrey 11 is slidably mounted.

ment withthe aperture 16 the driving clutch member 12 and'the driven clutch member 13 will be operatively interengaged the drive.

A s rin 17 normall ur 'es the clutch he I J a '11 into 0 erative en' a einent with the as- D erture 16 in the driving clutch member 12;

A clutch control lever 18, pivoted upon the frame at 19, is provided with a camming arm 20 which normallylies in the path of the heel 21 of the clutch key 11 and th'erebycams the clutch-key 11 in the direction of the'arrow 22, against the force of the spring 17, thereby disengaging the same from the driving clutch member 12.

When it is desired to effect an engagement between the driving clutch member 12 and the shaft 6, thereby to reciprocate the punch, the clutch control lever 18 is deflected in such a manner as to retract the cam arm'20 from operative alignment with'the heel 21 of the clutch key 11. A friction brake 23 surrounds the driven clutch member 10, thereby to check the inertia of'the crank shaft 6,'punch slide 3 and connecting rod'8 when the same are disengaged from T Upon the continuously revolving driving The sheet or jacquard strip 29 is supported uponthe table 28. ,4

The table 28 is provided with a longitudinal dovetailed guide rail 30, upon which a rack member 31 is slidably mounted, having uniformly spaced transverse ratchet ieeth 32 upon its upper surface.

.The leading end of the sliding rack 31 carries a clamping member 33 in which one end of the sheet to be punched, such as the jacquard strip 29, is detachably secured for the purpose of propelling past the punching device. Thus the clamp 33 is provided with a recess 34 in which-theend of the.

strip fits, and is also provided with a spring pressedplunger or pin 35 adaptedlo enter a correspondlng aperture 36 in the end of "the jacquard strip, thereby to retain the same in fixed spaced relation with respect to the sliding feed rack 31. The spring 3.

confinedbetween the transverse pin 38 and the upper guide and supporting bracket 39,

serves to maintain the plunger in its lowermost position.

v The lower die 40' is detachably secured in the'. table 28 with its upper surface flush with the upper surface of the table, while a stripper plate ll is fixedlydmounted above and in operative alignment with the lower die 40, spaced therefrom a distance substantially equal to the thickness of the sheet 29 r to be punched, as shown particularly in Figures 14 and 15.

The punch 42 is mounted in the punch slide 3 in operative alignment with the die 40. r

A pair of fixed guides s3 and 4 4 serve to guide the jacquard 29 as it enters between the punch and die.

Sheet propelling and punch controliing mechanism I V The lower shaft 25 carries a bevelled gear 45 which is in mesh with a similar bevelled gear 46 carried by an inclined shaft 47 which is journalled at 41 8 in a bearing bracket 49 (Figures 2 and -il7in turn is connected to a horizontal shaft 50, through a universal joint 51; said hori-- zontal shaft in turn being journalled at 52 in said bearing bracket 49. To the free .end of the shaft '50 a concentric disk 53 is 6' secured, likewise ournalled in the bearing bracket 49, which in turn carries an eccentric pin Uponthe eccentric pin 54 a pawl 55 is loosely mounted, having its lower end 56 in operative alignment withthe teeth 82 of the rack 31. p v

The arm '57 of the pawl member 55 is urged upwardly by the helical spring 58, the upperend of which is supported by a suitable bracket 59.

The eccentricity of the pin 54 is such as "to cause thelower end 56 of the pawl 55 to be 'displaced laterally with each revolution 1 of they shaft 50 and disk 53',- the distance of one tooth (32) on therack 31, thereby displacing the rack 31 as well as the jacquard or other strip 29 carried thereby, the distance of one tooth (32);

A rotation of the shaft 50 is so timed with respect to the clutch key aperture 16 in'the driven clutch member 12, as to effect the intermittent propulsion of the rack 31, and hence of the jacquard strip 29, during the interval whent-hepunch 42 is removed from the die 40, that is, during the latter part of the vup-stroke and the beginning of the down-stroke of the punch.

The operation of the clutch key 11 of the punch is effected by the pattern, wheel 60 carried by the horizontal shaft 61 which is likewise d iven in a continuous manner from the horizontal shaft through the train of gears shown particularly in Fig lures 1, 2 and 3.

Thus the shaft 25 carries a'driving pinion 62, which 18 m mesh with a gear 63, carried by a counter-shaft ea journalled in suitable The shaft carried by a second counter-shaft 69, journalled in the bearings 7 0 similarly carried by the lower frame structure 66. The second counter-shaft 69 carries a pinion 71 which is in mesh with a gear 72 carried by the pattern wheel shaft 61, which latter is journalled in the two bearings 73 carried by the lower frame structure 66.

The pattern wheel 60, shown enlarged in Figure 12, is a cup-shaped disk having a series of spring-pressed plungers or pins 74 mounted in the face 'T5'thereof. The springpressed plungers or pins '74 are uniiorni'ly spaced at predetermined intervals throughout the periphery of the pattern wheel 69. Any suitable number of pins 74 may be provided, though in the instant machine pinsare used, as this number has been found to be suitable for one of the purposes for which this machine is intended, (though in the drawings the full fifty pins are not shown).

Each spring pressed plunger or pin is slidably mounted in a suitable bearing 76, and is provided at its inner end with two flanges 7'7 and 7 8 spaced from each other a suitable distance. A bracket 79 is provided within the pattern wheel corresponding toeach of the pins, 74 and secured by a screw 80 passing through the flange 81 of the pattern wheel. A helical compression spring '82 is confined between the inner end ofthe pin 7, 1 and the screw 80, tending to urge said pin outwardly. A spring-pressed locking bolt'83 is carried by the bracket 79, and actuated by a helicalcompression spring bracket .84, whereby the"pin 7st may be locked in its innermostposition with the outer end thereof flush with the face 75 of the pattern wheel thereof. This is accon plished by depressing the pin 74 inwardly, withdrawing the spring-pressed bolt 88 by means of its handle 85 and placing the free end of the lockingbolt 83 between the two iianges77 and 7 8 of the pin 74, thereby retaining said pin'inits inner position. By

so locking'the pin in its inner position'the same is rendered inoperative. Alvertical follower slide 86 is slidably mounted'in a pair of supporting brackets 87 and 88, and is arranged generallytangentt ally with respect to. the pattern wheel 60 and in operative alignment with thepins 'Tithereot, so as to'b e successively,engaged and raised upwardly by each of the pins 7A which may be in their outer or operative positions. 7

The upward displacement of the follower "slide 86 is transmitted to a lever 89 pivoted at'90 upon the lower frame structure 66,-to

which'lever the upper end of the slide 86 is pivotally fastened at 91. The free end of the lever89 is in turn connected-tothe tree end ofthe clutch controllever 18, by means of a'connecting rod 92, pivotally secured to the free ends of said two levers at 93 and 94 respectively.

The camming arm 20, forming the one end of the control lever 18, is urged upwardly into an operative position by a helical compression spring 95 which surrounds the ver tical rod 96, which is pivotally connected to said cumming arm 20, and the lower end 01' which passes through and is guided by a stationary bracket 97, which latter also supports the lower end of the spring .95. The connecting rod 96 is in turn connected with a manual control lever 98 through the connecting rod 99. Thus, by the depression of the manual control lever 98, the camming arm 20 may be retracted so as to permit the operation of the clutch key 11 and hence so to operate the punch.

The spring 95 therei'or serves normally to maintain the camming arm in its upper or operative position, thereby rendering the punch inactive, and the spring 20 also serves to niainta 1 the follower slide 86 in its lowcrmost position.

As each ctive pin 74 (a pin in its s the lower end of the snown in Figure 3), as the pattern wheel 60 revolves continuously in the direction of the arrow 100, the follower le 86 is raised a fixed distance, sullicient to retract the cammingarm Q0 and to render the punch active for one stroke.

As the jacquard strip 29 is therefore propolled intermittently in the direction of the arrow 101 (Figure 8) the punch 42 may be caused to act upon the acquard strip at predetermined irregular intervals as may be desired, by merely positioning the appropriate pattern pins Tl in the outer or active position and depressing the other pins.

Thus, to punch any particular pattern upon a acquard strip 29, it is merely necessary to set the pattern upon the pattern wheel 60,

by properlypositioning the pattern pins 7 1 thereof, and then to feed the jacquard strip '29 through the punch with the result as indicated in Figures 8 and 10.

The number of pattern pins 74: provided upon the pattern wheel 60 is greater than the number of positions or stitches of anyparticular design or pattern that may be desired, so that a jacquard strip 29 though containing punch positions or jacquard positions in excess of fifty, may be completely punched upon this machine, in a 3 fully automatic manner, by merely repeating the pattern I (of less than fifty positions) as often as the pattern may occur upon the particular jacquard strip.

Thus, for instance, a pattern of twelve positions occurring eight times upon the jacquard strip is set onthe pattern wheel 60 four times in succession, thereby utilizing fortynight pins ot the total 50; the remaining two pins being rendered in active and the jacquard strip is thus punched fully by two revolutions of the pattern I wheel 60;

' 7 block 102 is fixed at the first position of t each revolution of the pattern wheel.

is accomplished by a pair of cams 102 and 103 shown partlcularly 1n Figures 5, 0 and In order that there should be no gap on the j acquard. strip, between the first and second revolution of the pattern wheel 60, or between any two successive revolutions thereof, corresponding to the number of pattern pins at the end of the revolution which had not been used, (the two last 3 ins" in the above exam le it is necessary to render the strippropellix1g mechanism nactive fora period corresponding to the unused pattern pms at the end of This 110 are threaded throughsuitable apertures 111 and 112' in the two cam hloclrs 102 and 103 respectively, for the purpose of lining.

said cam blocks in any desired position along the annular channel 108. The cam he pattern on the pattern wheel, while the cam block 103 is positioned immediately after the last pattern position on the pattern wheel. 7 v a follower lever 113 is pivotally mounted at114 upon the stationary bracket 115 The lower-right angular end 116 of the follower cause the deflection of the follower lever 113 and 9 lever 113, is provided with a generally cylindrical follower roller or member 117, which is in operative alignment with the camming surtaceslO-l and 105 of the two cam blocks 102 and 103 respectively. Thus the cam block 102 at the beginning of the pattern-setting of the pattern wheel will in a manner indicated by the arrows 118 (Figure 1), while the cam. block 103, at the endot the pattern-setting, will cause an opposite deflection of the follower lever 113 as indicated by the arrows 119 (Figures 1 The upper free end 01 the follower lever 113 is pivotally connected, at 120, to one end of a horizontal slide 121 which is slidably mounted in a stationary guide 122. The free end 123 of the slide 1211s mclined as shown particularly in Figures 1 and 9, and is in operative alignment with a correspondingly inclined surface 124 of the jacquard propelling pawl arm 57.

VThus when the lever 113 is deflected in the direction ofthe arrow 119 (Figure 9) by the cam block 103, positioned at the end of the pattern-setting of the pattern wheel, the inclined end 123 ofthe slide 121 engages the inclined end 12 1 of the pawl arm 57, riding up upon the same, and thereby deflecting the pawl arm and retaining it in a deflected position with the operative end 56 thereof raised above and clear of the teeth 32 of the rack 31 and thereby automatically stopping the propulsion oi the jacquard strip. As the pattern wheel revolves further, the cam block 102, having an oppositely positioned cam surface 104, engages the follower 117 and deflectsthe lever 113 in the direction of the arrow 118 and thus retracts the slide 121 and again releases the pawl 56 into operative engagement with the teeth 32 of the rack31. By this means the propulsion or" the'jacquard strip is again initiated at-the beginning of the pattern-set ting andthe pattern may thus be repeated upon the jacquard strip without any gap or break between the successive revolutions of the pattern wheel. j I r In order automatically to stop the propulsion of: thejacquard strip when it is fully punched throughout its desired length stop 1253 is adjustably secured to the rack 31 by means or set screw 126. This stop 25, when properly set with respect to the end or the jacquard strip, will engage a pin 127 carried by theslide 121 and thereby move said slide forwardly into an operative position and thus render the propelling pawl 56 inactive.
